High ferro brake system is the key factor that security critical is run, and reliably must be stopped by high speed train under any running state.Advanced brake system must consider multiple special status: unloaded brake condition, fully loaded brake condition, wheel disc skid condition, emergency braking.No matter train uses mechanical brake, magnetic rail brake device, eddy-current brake or electric braking, and brake system should can guarantee the normal realization of braking function under any running condition.Such as, the speed per hour of the high speed railway of distributed AC servo system brake system is adopted can to reach 350 kilometers/hour.

Detailed description of the invention

For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar improvement when intension of the present invention, therefore the present invention is by the restriction of following public concrete enforcement.

The invention provides a kind of high ferro braking method, right for braking multiple wheel be arranged in order, wherein, take turns respectively to there being a brake equipment described in each.It should be noted that at this, describedly taking turns being the part that high speed train directly contacts with rail, described wheel being fitted on same axletree by two, left and right wheel hub and forming.On the one hand, described take turns right effect be guarantee high speed train can realize on rail run and turn to, and the whole quiet and live load of bearing from high speed train is passed to rail, also by the dynamic changes process that produces because of guideway irregularity to each parts on high speed train.On the other hand, high speed train driving and braking also taken turns realizing by described.

As shown in Figure 1, it is the flow chart of steps of the high ferro braking method of an embodiment of the present invention, comprises the steps:

Step S110, described brake equipment receives outside angular acceleration values, and obtains initial controling parameters value according to the functional relation between the outside angular acceleration values preset and controling parameters value.

When high speed train runs, in order to controlling run speed better, need to be realized applying braking force to wheel by brake equipment.That is, when high speed train runs, interact to the propulsive effort provided to wheel to the braking force applied and outside motor to wheel by brake equipment, control the running velocity of high speed train.

When needs control that high speed train carries out raising speed, reduction of speed or constant speed operation time, as, from 350 kilometers/hour of speed-raisings to 380 kilometers/hour, from 380 kilometers/hour of reductions of speed to 350 kilometers/hour or constant speed when running for 350 kilometers/hour, outside driving console, according to current speed value and goal pace value, can obtain outside angular acceleration values.

In order to obtain outside angular acceleration values better, such as, outside driving console has general control system, and this general control system presets external angular velocity value table according to current speed value and the inquiry of goal pace value, can obtain corresponding external angular velocity value.And for example, outside driving console has general control system, general control system has read-only memory (ROM) (Read-Only Memory), this read-only memory (ROM) stores default external angular velocity value table, general control system, according to the default external angular velocity value table stored in current speed value and goal pace value inquiry read-only memory (ROM), can obtain corresponding external angular velocity value.It is pointed out that this default external angular velocity value table when High-Speed Train Design and trail run time by experiment etc. link obtain, specifically how to obtain about default external angular velocity value table, please refer to existing techniques in realizing, do not repeat them here.So, outside angular acceleration values can be obtained better by default external angular velocity value table.

After brake equipment receives outside angular acceleration values, by the functional relation between default outside angular acceleration values and controling parameters value, can obtain initial controling parameters value, like this, brake equipment just can be taken turns applying braking force correspondence according to this initial controling parameters value.

Such as, functional relation in order to obtain initial controling parameters value better, between described default outside angular acceleration values and controling parameters value is:

${\stackrel{\·}{a}}_0=\mathrm{\β}{K}_0;$

Wherein, a ₀for described outside angular acceleration values.K ₀for described initial controling parameters value.β is constant, it is the transformational relation between controling parameters value and outside angular acceleration, namely the controling parameters value inputted, namely the relation between control signal value and wheel angular acceleration, for fixed value, be by during brake assembly design and trail run time the parameter value drawing of link such as by experiment, specifically how to obtain about β, please refer to existing techniques in realizing, do not repeat them here.So, by the functional relation between above-mentioned default outside angular acceleration values and controling parameters value: just can obtain initial controling parameters value better.

In order to introduce the functional relation between described default outside angular acceleration values and controling parameters value further: be described in detail at this, wherein, a ₀the initial controling parameters value K of input ₀calculate after being changed by β again.That is, when brake equipment receives initial controling parameters value K ₀after, e.g., K ₀for the voltage signal of simulation, so brake equipment will according to initial controling parameters value K ₀corresponding giving currently describedly is taken turns applying corresponding braking force, when the acceleration/accel of front-wheel to feeding back based on this braking force institute time is a ₀.Also can be understood as, K ₀with a ₀be respectively the relation of input and output, use a ₀derivative describe rate of change, i.e. a ₀rate of change by K ₀determine, then after considering the transformational relation between β this controling parameters value and outside angular acceleration, can K be calculated ₀.

Step S120, detects and obtains multiplely describedly taking turns right current angular value.

It should be noted that, in a practical situation, high speed train operationally, mutual application force can be there is between each compartment, as, thrust is or/and pulling force, these compartments can by these force transmission to the wheel of correspondence to upper, so, be presented as each take turns between also can produce and influence each other, if brake equipment do not consider each take turns between influence each other, directly take turns applying braking force according to described initial controling parameters value to correspondence, so, the braking effect of actual braking effect and expection can be caused to have deviation, and braking accuracy rate is poor.

At this, obtaining multiplely describedly taking turns right current angular value by detecting, condition can be provided for revising initial controling parameters value.

Step S130, according to preset current described take turns right: described current angular value, adjacent two described functional relations of taking turns between right current angular value, described outside angular acceleration values and described initial controling parameters value, obtain working control parameter value.

In theory, in order to obtain currently describedly taking turns right working control parameter value, should consider current described take turns to except current described take turns to except all take turns between interact relation, so, could consider more all sidedly each take turns between influence factor, to obtain more accurate working control parameter value, but in fact, because the data transmission between multiple brake equipment has delay constraint.That is, if consider current described take turns to except current described take turns to except whole wheels between interact relation after, each current described time of taking turns processing data, add each current described take turns to except current described take turns except all wheel will be longer to carrying out the data transmission time used, especially, when number of carriages is more to quantity with wheel, the time used will be longer.So, obtaining the current described time of taking turns right working control parameter value will be longer, but according to the requirement of high speed train real-world operation, need described brake equipment after the initial controling parameters value of reception, describedly take turns carrying out braking response to current within the extremely short time, to avoid delaying the problem that high speed train speed runaway occurs when braking.So, just based on this problem of delay constraint, if go to revise initial controling parameters value to obtain working control parameter value by above-mentioned this consideration mode, obviously reasonable not.

Based on this problem of delay constraint, in step s 130, which, only consider that right current angular value is describedly taken turns in current described adjacent two of right front and back of taking turns, greatly to reduce the impact that delay constraint brings, and by each current described take turns to before and after all considering adjacent two describedly take turns right current angular value, thus make all brake equipment compositions on high speed train under delay constraint, have the brake system of harmony, its harmony preset current described take turns right: described current angular value, describedly take turns right current angular value for adjacent two, functional relation between described outside angular acceleration values and described initial controling parameters value, to delay constraint, there is good comformability.

The traditional braking method poor relative to accuracy rate, the present invention is by above-mentioned steps S130, can take into account simultaneously delay constraint and each wheel between influence factor, and describedly take turns right initial controling parameters value to current and revise, to obtain currently describedly taking turns right working control parameter value, when each current described wheel described is taken turns when braking to the working control parameter value all by correspondence to current, so, multiple current described take turns to multiple brake equipments corresponding respectively just can form the brake system of the multiple agent cooperatively interacted, the braking effect deviation of its braking effect and expection is minimum, braking accuracy rate is higher.

In order to obtain currently describedly taking turns right working control parameter value better, such as, described default current described take turns right: described current angular value, adjacent two described functional relations of taking turns between right current angular value, described outside angular acceleration values and described initial controling parameters value are:

$\stackrel{\·}{K}=K_0+\mathrm{\γ}[(a_e-a_d)+(a_e-a_f)+(a_e-a_0)]$

Wherein, γ is constant, and K is described working control parameter value, a _edescribedly right described current angular value is taken turns, a for current _dand a _fbe respectively current describedly to take turns right adjacent two and describedly take turns right described current angular value.As can be seen from above-mentioned functional relation, current described size of taking turns right working control parameter value K is subject to current described initial controling parameters value of taking turns brake equipment to correspondence, with adjacent two described joint effects of taking turns the braking effect of right brake equipment.Wherein, described wheel is presented as current angular value to the braking effect of the brake equipment of correspondence.

In order to introduce further described default current described take turns right: described current angular value, adjacent two described functional relations of taking turns between right current angular value, described outside angular acceleration values and described initial controling parameters value: $\stackrel{\·}{K}=K_0+\mathrm{\γ}[(a_e-a_d)+(a_e-a_f)+(a_e-a_0)],$ Be described in detail at this, K and K ₀+ γ [(a _e-a _d)+(a _e-a _f)+(a _e-a ₀)] be respectively the relation of input and output, use derivative the rate of change of K is described, namely the rate of change of K is by K ₀+ γ [(a _e-a _d)+(a _e-a _f)+(a _e-a ₀)] determine, so, based on K ₀, then consider γ, currently describedly take turns right adjacent two and describedly take turns right described current angular value a _dand a _f, and described current angular value a _ewith outside angular acceleration values a ₀impact after, can K be calculated.

It should be noted that, when multiple be arranged in order describedly take turns centering, lay respectively at that two of head and the tail are current describedly takes turns right a _dor a _fequal zero, be namely positioned at the first current described take turns to one that only need consider to be adjacent rear described take turns to, be positioned at tail position current described take turns to one that only need consider to be adjacent front described take turns to.

Step S140, described brake equipment is taken turns braking the described of correspondence according to described working control parameter value, and returns step S110.

When described brake equipment to be taken turns after braking to correspondence described according to described working control parameter value, return step S110, so, can revise controling parameters value initial described in each, obtain corresponding described working control parameter value, thus can guarantee that high speed train realizes the higher braking procedure of accuracy rate in operational process.
